Исключение при создании сеанса hibernate 4

Question

Когда я запускаю свой тестовый класс, он запускает исключение вместо создания сеанса. Вы можете увидеть в консоли, как

log4j:WARN No appenders could be found for logger (org.jboss.logging). 
log4j:WARN Please initialize the log4j system properly. 
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

мой боба как:

package com.live.beans; 

public class User { 

    private int id; 
    private String Name; 
    private String email; 
    private String password; 

    public int getId() { 
     return id; 
    } 

    public void setId(int id) { 
     this.id = id; 
    } 

    public String getName() { 
     return Name; 
    } 

    public void setName(String name) { 
     Name = name; 
    } 

    public String getEmail() { 
     return email; 
    } 

    public void setEmail(String email) { 
     this.email = email; 
    } 

    public String getPassword() { 
     return password; 
    } 

    public void setPassword(String password) { 
     this.password = password; 
    } 

    public User(int id, String name, String email, String password) { 
     super(); 
     this.id = id; 
     Name = name; 
     this.email = email; 
     this.password = password; 
    } 

    @Override 
    public String toString() { 
     return "User [id=" + id + ", Name=" + Name + ", email=" + email 
       + ", password=" + password + "]"; 
    } 

} 

User.hbm.xml:

<?xml version='1.0' encoding='utf-8'?>

Мой класс HibernateTest.java:

package com.live.presentation; 

import org.hibernate.Session; 
import org.hibernate.SessionFactory; 
import org.hibernate.cfg.Configuration; 

import com.live.beans.User; 

public class HibernateTest { 

    private Session session; 
    private static SessionFactory sessionFactory; 
    private static ServiceRegistry serviceRegistry; 

    public static SessionFactory createSessionFactory() { 
      Configuration configuration = new Configuration(); 
      configuration.configure("hibernate.cfg.xml"); 
      serviceRegistry = new ServiceRegistryBuilder().applySettings(
        configuration.getProperties()).buildServiceRegistry(); 
      sessionFactory = configuration.buildSessionFactory(serviceRegistry); 
      return sessionFactory; 
    } 
    private void openSession(){ 
     SessionFactory sessionFactory = createSessionFactory(); 
     Session session = sessionFactory.openSession(); 
     session.beginTransaction(); 
    } 

    private void closeSession(){ 
     session.getTransaction().commit(); 
     session.close(); 
    } 

    public HibernateTest() { 
     openSession(); 
     User p = new User(1, "Ali", "ali@gmail.com", "password"); 
     session.save(p); 
     System.out.println("sauvegarde reussi"); 
     closeSession(); 
    } 

public static void main(String[] args) { 

    new HibernateTest(); 
}

НО У меня есть исключение, когда я достигнуть на этой линии, которая находится в HibernateTest.java класс (я имею в виду в то время отладки):

configuration.configure («hibernate.cfg.xml»);

Хотя я использую configuration.configure(); ,У меня та же проблема.

Пожалуйста, кто-нибудь может мне помочь!

Answer 1

Ресурс сопоставления является неправильным. Используйте/для разделения папок.

Проверьте конфигурацию следуя section of Hibernate Documentation

И вам не нужно добавлять в спящий режим. префикс в свойствах имени

<?xml version='1.0' encoding='utf-8'?> 
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> 
<hibernate-configuration> 
    <session-factory> 
    <property name="connection.url">jdbc:mysql://localhost/ment</property> 
    <property name="connection.driver_class">com.mysql.jdbc.Driver</property> 
    <property name="connection.username">root</property> 
    <property name="connection.password"></property> 
    <property name="dialect">org.hibernate.dialect.MySQLDialect</property> 
    <property name="show_sql">false</property> 
    <mapping resource="com/live/hibernate/User.hbm.xml" /> 
    </session-factory> 
</hibernate-configuration> 

Edit: Метод openSession использует метод области видимости переменных вместо ваших переменных класса, так что вы должны быть исключения нулевого указателя в заявлении session.save(p) наверняка. Внимательно просмотрите свой код !. Я также предлагаю вам добавить findbugs-maven-plugin, чтобы обнаружить ошибки сообщества в вашем коде. Вы можете использовать его в фазе компиляции, чтобы сбой сборки, когда есть такие ошибки. Here is simple tutorial.
